RadComboBox for ASP.NET AJAX

The OnClientItemChecked client-side event occurs immediately after a particular item is being checked.

The event handler receives two parameters:

1. The instance of the combobox firing the event.

2. An eventArgs parameter containing the following method:

   • get_item returns the item that has just been checked.

   • get_domEvent() returns the DOM event object.

Use this event to respond to the newly checked item:

<script language="javascript" type="text/javascript">
    function OnClientItemChecked(sender, eventArgs) {
        var item = eventArgs.get_item();
        sender.set_text("You checked " + item.get_text());
    }
</script>
